In this paper the problem of signal propagation in networks of excitatory elements is studied. It is found that the geometry of signal transmission paths depends crucially on how an excitatory element responds to a stimulus. Two types of responses are defined: fast and slow. In the slow response case the signal transmission paths are in the same universality class as optimal paths in the limit of strong disorder. The signal transmission paths formed in the fast response case constitute possibly a new universality class.
本文研究了兴奋性元件网络中的信号传播问题。研究发现,信号传输路径的几何形状关键取决于兴奋性元件对刺激的响应方式。定义了两种响应类型:快速响应和慢速响应。在慢速响应情况下,信号传输路径与强无序极限下的最优路径属于同一普适类。快速响应情况下形成的信号传输路径可能构成一个新的普适类。
